Stainless Steel Sanitary Straight Diaphragm Valves with Silicone Membrane

Diaphragm valves: Manual or air actuated.are specially designed for hygienic and asepsis processes in pharmacy industry.This valve is excellent for controlling as well as on/off fluid.
Diaphragm seals the valve body and seat.The is no way to contact the environment.So this valve is suitable for asepsis process.When the valve is off.The pressure seal that holding up diaphragm moves towards to the sealing face of valve body.When the pressure plate moves,the diaphragm bending.forced towards to seat area of body center.So that to shut off the flow path to valve body.The relevant of valve body and pressure plate prevents the diaphragm pressing.The valve can be manual and air actuated,also can be operated by control top and soleniod valve.
